If the TOS designers had had any inkling that we fans would be scrutinizing decals applied to a model kit 45 years after the fact, and if they had had any foreknowledge of Internet-era lingo, then I suspect Constellation's registry number would have been made from two decal sets, with 7s inverted, resulting in a number of NCC-L0L.![]()
Or they might have not shown the registry number at all, just having that section of the ship be one of the parts blown off by the planet killer.
				
		


 (wouldn't that be XVII/01 ?).
